Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Instapaper

  • Full text search across saved articles is Premium only, at $5.99 a month or $59.99 a year
  • Free accounts are limited to 5 notes a month, against unlimited on Premium
  • Text to speech, speed reading and the permanent archive are all Premium only
  • The free web experience carries advertising

Userscripts

  • Safari cannot let extensions bypass a site's Content Security Policy, so strict sites produce "Refused to execute a script" errors that the @inject-into workaround does not always fix.
  • Apple only. There is no Chrome, Firefox or Edge build, so it cannot be a cross-browser answer.
  • iCloud sync is documented as having delays, which is awkward when editing the same script on two devices.
  • Requires macOS 12 and Safari 14.1, or iOS 15.1, so older Apple hardware is excluded.
  • GPL v3 means a commercial licence is required for non-open-source use, which matters if you are embedding rather than just using it.

Answered from the vendors’ own pages

Instapaper: What is the cost of Instapaper?

Instapaper costs $5.99 per month or $59.99 per year. The yearly plan saves over 15% compared to the monthly rate.

Source
Userscripts: Is Userscripts for Safari free?

Yes, free on the App Store and licensed under GPL v3. A commercial licence is required for use in something that is not itself open source.

Source
Instapaper: Does Instapaper offer a free trial?

No trial period is offered. The subscription starts immediately upon purchase.

Source
Userscripts: Does it work on iPhone?

Yes, on iOS and iPadOS 15.1 or later, which makes it one of the few ways to run userscripts on an iPhone.

Source
Instapaper: What features are included in the paid subscription?

Premium features include full-text search across all articles, permanent archiving, PDF reading, unlimited notes (free tier limited to 5 per month), Kindle integration, AI-powered text-to-speech, and speed reading up to 3x faster. The paid version also removes advertisements.

Source
Userscripts: Why do I get "Refused to execute a script" errors?

Safari does not let extensions bypass a site's Content Security Policy the way other browsers do. The documented workaround is changing the script's @inject-into setting, though it does not resolve every case.

Source
Userscripts: Do my scripts sync between Mac and iPhone?

Yes, over iCloud, though the project notes the sync can be delayed rather than immediate.

Source
Userscripts: What are the system requirements?

macOS 12 or later with Safari 14.1 or later, or iOS and iPadOS 15.1 or later.
